--- Comment #24 from Ilia Mirkin <[email protected]> ---
Looks like this bios hard-codes a 4K return size for each bios chunk fetch.
There is a "fast" and a "slow" method in nouveau... the fast one grabs it all
in one go, while the "slow" one does it 4K at a time.

In drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c, try commenting out the
line

                { 0, &nvbios_acpi_fast },

For some reason we're not detecting that it's fetching a bad bios...
